HYDROCARBON BURNER.

Application filed August 19, 1921.

To all 'zu/ont t may concern Be it known that I, CHARLES, EDWARD CoRADO7 a subject of the King of Great Britain, and resident of the city of Winnipeg, Province of Manitoba, Dominion of Canada, have invented certain new and useful 1mprovements in Hydrocarbon Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to hydrocarbon burners of the type disclosed in my pending application Serial No. 374,225, and has for its object to provide a burner containing as a component part thereof a combined means for feeding the wick and snufling or trimming the same, the snuffer being adapted to be moved in a straight line across the top of the wick by a direct thrust from a manually operated member. A further object is to provide a burner in which a more uniform distribution of air to the zone of combustion can be obtained and which may be manufactured at a relatively low cost.

For full comprehension, however, of my invention, reference must be had to the accompanying drawings in which similar reference characters indicate the same parts, and wherein:

Figure 1 is a side elevation of a burner constructed according to my invention;

Figure 2 is a plan view thereof with the cap partly broken away;

Figure 3 is a transverse sectional view taken on line 3 3 Figure 1 and looking in the direction of the arrows; and

Figure 4 is a sectional view taken on line 4-4 Figure 2.

The accompanying drawings illustrate the preferred embodiment of my invention which consists of a burner comprising a body or base 2 and a cap 3. The former consists of a hollow shell containing a chamber 4 and is of reduced diameter and screw-threaded as at 5 for connection with the usual oil font 6. The side wall 7 of the shell is provided with a circumferential series of spaced openings 8 which are adapted to prevent the accumulation of gas in the chamber 4 and such wall is extended upwardly above the top 9 of the shell as at 10 and provided with a series of air inlet openings 12 which admit air to the space between the cap and the top of the shell. The wick tube which is indicated at 13 extends upwardly through the body to a point at which its top will be positioned a short distance below the high- Speccaton of Letters Patent.

est point of the cap. The latter is hinged as at 14 upon the wall 10 and is of the usual dome form having a flame opening 15 in its top and having a circumferential flange 16 at its .lower edge which constitutes a gallery for supporting a lamp chimney 17, the gallery, when the cap is down, being adapted to rest upon the upper edge of the wall 10. This upper edge is notched as at 18 to provide additional air inlet openings. The portion of the gallery between the point at which it joins the dome and chimney is provided with a circumferential series of ports 19 which effect communication between the space immediately above the burner body.

ln order to provide a more even distribution of air to the Zone of combustion the dome of the capv is constituted by a double deck structure the outer deck being indicated at 21 and the inner at 22. The inner deck consists of a pair of deflectors 23 which are located one at each side of the flame opening with their upper ends extending upwardly to a point slightly above the top of the wick tube.

To retain the lamp chimney upon the gallery the latter is provided with a pair of upwardly extending` lips 24 and 25 with which a spring clip 26 is adapted to cooperate. The latter is located at a point on the gallery diametrically opposite to the point at which the cap is hinged to the body and such clip also serves to secure the cap upon the body when down. To this end the clip is extended downwardly below the gallery from its point of connection thereof and turned inwardly and upwardly in substanw Y tially U form, the` upwardly extending arm of the U being of increased width as at 30 for engagement with a stop 31 rigidly1 mounted upon the wall 10 of the body and the stop is of channel form presenting laterally extending flanges 32 havin-g rounded edges The extreme upper end extends through an opening 34 in a radially extending lug 35 on the gallery and terminates in the clip 26. The means for snuliing the wick in the embodiment illustrated is combined with the means for feeding the same, but to meet certain conditions it may be desirable to have the snuffer operable independently of the wick feeding means. The latter consists of a sprocket shaft 4() eXtending transversely through the body of the burner and journalled in the side wall thereof and is provided with the usual wick feedingv sprocket il the teeth of which are adapted to extend through a slot in the wick tube into engagement with the wick.

rThe portion of the sprocket shaft which extends through the bod)v of the burner is of round cross-section but that located exteriorly of the burner and which extended a slight distance from the same is of square cross-section indicated at 42 and slidahly earries a handle of truncated conical form having` a cylindrical extension 43a. and this handle has au axial boring of square cross-section to receive the shaft portion 42 thereby enabling` the latter to be turned by the handle and permitting; axial movement of the latter thereon. The snuffer proper consists of a rigid strip ,44 of substantially inverted d form the lower ends of the arms of which are rigidly connected to the siaced parallel push. rods t5 and et?) which are slidably mounted in the wall 10 of the burner and located on opposite sides of the wick tube. the strip being` adapted to straddle the latter in its snuliingr movementand of a height to just clear the top of the tube.

rthe push rods are located above and in juxtaposition with. the sprocket shaft and their outer ends are connected to the handle etiwhereby axial movement of the handle produces a kstraight line. movement of the strip ad across the top ofthe wick tube and between the detleetors 23, the point of connection between the push rods and the handle beine; effected by offsetting` the outer end of the arm -l-.G to a point alongside the arm t5 and termimiting` the two rods in a downwardly extending eye 4S which eneirclcs a. reduced portion 49 on the cylindrical extension 45 on the handle. ln order to yieldingly maintain the handle in position with the strip `lit located at one side of the wick tube. a helical spring` 50 encircles the shaft 40 and bears between the journal and the adjacent end of the handle while the axial movement of the latter away from the burner is limited by a pin 51 rigidly mounted in the outer end of the shaft. To provide a firm grip on the handle it may be knurled as at Although l. have described an embodiment en'iploying-two push rods. under certain conditions it may be desirable to employ only one.
